A Nebraska mother was sentenced to 64 to 102 years in prison Monday for sexually assaulting two of her young daughter’s friends during sleepovers at her home, a report said.

The sentencing of Christina Greer, 38, comes after she was found guilty in March of three counts of sexual assault for abusing two boys, ages 12 and 13, in 2018 and 2018, the Omaha World-Herald reported.

Greer gave the minors alcohol and marijuana-infused gummy bears during weekend sleepovers in 2017 and 2018, prosecutors have said.

She also told them to delete evidence from their phones and to not tell anyone about their sexual encounters, according to prosecutors.

Investigators found sexually explicit photos of Greer from one of the boys’ phone, court documents show.
